of Delaware a corporation Application December 30, 1938, Serial No. 248,558 25 Claims. 01. 178-42) The present invention relates to printing telegraph apparatus and more particularly to a page printing telegraph apparatus suitable for displaying in a single viewing location both curnism for normal line feed operations, a secondary paper feed mechanism adapted to supervene the normal line feed mechanism, and means controlled by spaced marginal openings in the paper strip to limit the movement of said supervening paper feed mechanism.

Specifically, in the remote control of printing telegraph apparatus employed in projection systems, the receiving stations at which the news items are printed are provided with stationery having alternate blank and previously prepared advertising areas. To control from a transmitting station the'presentation of news items and advertising matter on the screen, the present invention provides for the use of stationery having perforated or notched edges, wherein the notches in the two edges are staggered, the notches along one edge governing the display of news items, and the notches along the opposite edge controlling the display of advertising matter.

The platen of the printing telegraph apparatus employed with the present invention may be rotated either in the normal manner in response to the operation of the standard line feed mechanism of the apparatus, or by means of an auxiliary feed means, through gears and a belt or chain drive arrangement wherein driving power is obtained from the main power shaft of the printing apparatus. When it is desired to display an advertisement in the printer, the operator presses a key, designated Advertisement key on the keyboard, which causes a function lever in the printing apparatus to be selected, which closes a contact momentarily, thereby establishing a series circuit through a control relay and a clutch electromagnet. 'The relay locks, forms a holding circuit, and as the armature of the magnet is attracted it withdraws the pawl from the clutch ratchet, thus permitting the clutch to rotate freely which, through associated pulleys and belts, causes the platen to rotate correspondingly to feed the stationery continuously until a pair of contacts encounters a notch in the edge of the stationery, at which time the .contacts act to'short circuit the relay and themagnet, causing the relay to open the holding circuit and causing the magnet to release the pawl to engage the clutch ratchet, thus arresting the 6 movement of the platen. If it is desired to dis- .play'news items, the News key. is'depressed by theoperator, resulting in the selection of a function lever in the printer and the control thereby of a relay and magnet corresponding to them described response to the Advertisement key to effect the feeding of the stationery in like manner, until a notch in the opposite edge of the stationery encounters a pair of contacts, which act to short-circuit the control relay and clutch operating magnet similarly to the manner previously described in connection with the adv'ertising matter.

The above objects and features of the invention will be better understood from the following description taken in conjunction with the accompanying drawingswherein,

In' the accompanying drawings, like, reference characters indicate similar parts throughout the several views. For a complete understanding of details not disclosed herein, and which form no part of the present invention, reference may be had to U. S. Patent No. 1,904,164, isssued April 18, 1933 to- S. Morton ct a1.

Having reference to Figs. 2 and 3, a printing apparatus to which the feeding and display mechanism of the present invention isapplied comprises a typing unit (shown generally in section in Fig. 2) which incudes a primary selecting mechanism, indicated generally as l1 (Fig; 3),which is of the sword-and-T type disclosed in U. S.. Patent No. 1,745,633 (fully disclosed in the first mentioned patent), and a secondary selector or selector vane assembly, indicated generally as 12.

The selector vane assembly 12 controls, through a series, of hell cranks l3 (comparable to bellcranks 44 to 43 shown in Fig. 1 of Patent No. 1,904,164), a corresponding series of curved code bars I4 carried in a movable type carriage. As set forth in the first-mentioned patent, this type carriage, indicated generally as I5, is movable longitudinally with respect to a stationary platen indicated generally as I6. The type carriage I5 also carries a ribbon feed mechanism, indicated generally as IT.

Referring particularly to Fig. 3, a motor I8 supplies power through its pinion I9 and a gear 20 to a main operating shaft 2I which carries the spacing mechanism, indicated generally as 22, and the selector cam assembly, indicated generally as 23. As is known in this type of device, power is communicated from the motor to an operating cam assembly carried on shaft ZI through a grab clutch, such as 25. Portion 24 of grab clutch 25 is pinned to and constantly rotates with the shaft 2!, which has also frictionally connected thereto the spacing mechanism 22 and the selecting cam assembly 23. Portion 24 is cooperatively engageable with the splined portion 26 when throw-out lever 2! is operated in timed relation with the reception of code signals.

Positioned parallel to the main operating shaft 2I.,is a rock shaft 42 (Fig. 2) on which are (not shown) in proper timed relation in the operative' cycle, functions to reciprocate a pull bar operating member 44. As more fully described in Patent 1,904,164, the selector magnet II in response to code signal impulses controls through the selecting cam assembly 23 a series of elements 45 (Fig. 3) articulated to the selector vanes of the selector vane assembly I2. The setting of the selector vanes I2 in accordance 40 with a received code combination of impulses is transferred through the bell cranks I3 to the series of curved code bars M to cause an alignment of notches therein. Therefore, when the pull bar bail 44 isoperated leftwardly (as viewed in Fig. 2) by the printing bail 43, a pull bar 4% drops into the aligned notches and, by means of its shoulder 49, is picked up by the bail 44 to cause, through the gear and rack articulation between said pull bar 46 and the type bar 41 associated therewith, the rotation of said type bar about its pivot 45 to bring the type face thereon into printing relation with the platen I6. The spacing mechanism 22, which is operated following the printing of a character, controls through gear 28, gear 29, shaft 30, gear 3| (Fig. 2) and spacing rack 32, the movement of the type carriage I5 to form character spaces.

Associated with the selector vane assembly I2 are a series of function levers, indicated generally as 5! (Fig. 3), for performing the various normal functions; for example, line feed, platen shift, platen unshift, as well as the special functions of controlling the display of news items or advertising matter in accordance with the present invention. The function levers 5| are pivotally mounted on a common shaft 52 and are guided in a function lever comb 53. Function levers 5i are normally biased in a counterclockwise direction (as viewed in Fig. 2) by a spring 54 individual to each function lever. Function levers 5| are normally maintained in the position shown in Fig. 2 against the pull of their spring 54 by a rod 55 carried by the bail 40. The platen I5 is rotatably carried on a shaft 56 journaled in the side members 5! and 58 of a platen frame assembly. Integral with the platen I6 is a line feed ratchet 59. The platen side frames 5! and 58 are pivotally mounted to the printer side frames BI and 62, respectively.

Having reference to Fig. 4, there is shown pivotally mounted on the platen side frame 58 a bell crank lever 63 for controlling the line feed operation. Pivotally connected to the upper extremity of the vertical arm of lever 63 is a line feed pawl 64 which cooperates with the line feed ratchet 53. The horizontal arm of the bell crank 63 is pivotally connected to the. upper end of a rod or link 65, the lower end of which (as disclosed in Patent 1,904,164) is operatively related to the line feed function lever of the series of function levers 5|. Thus, when the function lever bail 46 is rocked in timed relation with the reception of the line feed code signal, the function lever bail rod 55 is lowered, thus permitting the line feed function lever to register with the vanes I2 under the action of its spring 54 to cause, through the aforementioned operative relation, the downward movement of rod 65.

The downward movement of rod 65 causes the clockwise rotation of bell crank 53 (as viewed in Fig. 4) to actuate the line feed pawl rightwardly to engage a tooth on the ratchet 59 to rotate the platen I6 one step in a line feeding direction. On the upward stroke of the rod 55, the lever 63 is actuated counterclockwise and leftward motion is imparted to the pawl 84 in preparation for a succeeding line feed operation. Moreover, as pointed out in Patent 1,904,164, the movement of pawl 64 may be adjusted to cause the platen I6 to be rotated two angular steps to perform double spacing. It is, of course, understood that, as is usual in page printers pressure rollers 66 are provided to cooperate with the platen It to cause the line-by-line motion of the paper 61 which is unwound from a. paper supply roll, not shown.

Also, pivotally connected to side frame member 53 of the platen frame assembly (Fig. 4) is the upper end of a rod or link II, the lower end of which is operatively connected or related to the platen shift and platen unshift function code levers of theseries. of function levers 5|, so that .upon the selection of the shift function lever, for example, the rod II will be actuated downwardly to move the line of printing on the platen I6 upward into alignment with the upper row of characters on. the type bars 41.

Conversely, when the unshift function code lever is selected, the rod II will beactuated upwardly, to rock the platen frame assembly counterclockwise to bring the line of printing again into alignment with the lower row of characters on the type bars 41.

The paper 61 in passing around the platen I6 is directed. in front of a backing plate 12 T9 supported by side frame '62. The contact roll- 75 'ers I6. and 11 ,(Fig. 2) cooperate with notches 8I'-A and BI- -N (Fig. 1) cut in themarginal edges of the paper 61 for control of the paper feeding and display mechanisms, as yet to be explained. J

A shaft 82 is journaled in the side frame BI of the typing unit, and, as seen in Fig. 1, carries a pulley 83, which is connected by a belt 85 to a pulley 84, fixed to the main operating shaft 2I. The pulley 83 is frictionallyrelated to the shaft 82 by a friction clutch comprising the flanged collar 86, apair of discs of friction material 8I, washer 89, and a compression spring 88 positioned between the washer 89 and a washer 9|. The frictionclutch just described is adjustable" by means of a nut 92. Loosely carried on the shaft 82 is a member 93 of an overrunning or one-way clutch,.the outer portion of which comprises a ratchet 94 fixed to said shaft. Ratchet 94 of the one-way clutch drives the portion 93 through the instrumentality of rollers 95. Integral with the portion 93 is a grooved pulley 96 (Fig. 1). The platen assembly side frame 51 is pivoted to the printer side frame 6| by means of a fixed stud shaft 91, Fig. 1 and rotatably mounted on the fixed stud shaft 9'! is a member comprising a grooved pulley 98 integral with a gear 99. The grooved pulley 98 is connected to the grooved pulley 96 by means of a belt NH. The gear 99 is meshed with a gear I02 integral with the platen I6. Cooperating with the-ratchet 94 is the armature I03 of a slow-to-release magnet I04 carried on a bracket I05 secured to the side frame 6|. The armature I03 is normally urged in a clockwise direction into engagement with the ratchet 94 by a spring I06.

The constantly rotating shaft 2| imparts, through the groove pulley 84 and belt 85, constant rotation to the grooved pulley 83, which is permitted to rotate on the shaft 82 through the instrumentality of the friction clutch associated therewith. Under these conditions, and with the magnet I04 de-energized, the pawl or armature I03 holds the ratchet'94 against rotation, the pulley 83 slipping on the shaft 82. Now, when the magnet I04. is energized in a manner which will presently be explained, the armature I03 is attracted and hence is withdrawn from engagement with the ratchet 94, whereupon the friction clutch will be effective to cause the rotation of the grooved pulley 83 to be imparted to the shaft 82 tov impart, in turn, rotation to the ratchet 94 of the one-way clutch, which, through the rollers 95 will impart like rotation to the portion 93. The rotation imparted to portion 93 is in turn imparted to the grooved pulley 96 which, through the instrumentality of the belt IOI. imparts rotation to pulley 98, and thereby to the gear 99. The counterclockwise rotation imparted to gear 99 imparts clockwise rotation to the gear I02 associated with the platen I6. This rotation is imparted to platen I6 independently of the bell crank 63 and pawl- 64, causing the ratchet 59 to rotate only against the action of detent 60, so that the paper 61 is advanced around the platen I6 and over the backing plate I2 under the control of the one-way clutch comprising members 93, 94, and 95. The paper 61 thus is passed around the roller'I3 and through the rollers I4 and I5, and also through the contacts I6 and TI to a papertake-up reel (not shown). I I

- The circuit for the slow-to-release magnet I04 is controlled by contacts I01 and I08, 5, which are inturn controlled by function levers I09 and H0, Fig. 2, respectively. As viewed in Fig. 2, "the function'levers I09 and I More each provided with rearwardly extending tail portions which cooperate with the contacts I01 and I08.

Having reference to Fig. 5 which is a diagrammatic view of the electrical circuit arrangement for controlling the paper feeding mechanism of the present invention, the paper 61 is shown in plan view and has marginal notches 8I-A and 8I--N; Itis understood that the position of the notch at the contacts I6 and IT at the lower edge of sheet 61 in Fig. 5 is only a transit position to enable (as will presently be explained) the short circuiting of electromagnets I04 and I2I. The normal position of the notch and contacts I6 and TI is as shown in connection with contact bank I9 in Fig. 1. The same explanation applies to the notch and contacts I6 and 11 associated with contact bank I8. The contacts I01 and I08 are shown diagrammatically as being controlled by the function levers I09 and H0, respectively. For the purposes of the present description, function lever IIO will be considered as the news function lever, and the function lever I09 will be considered'as the advertisement function lever. When it is desired to display or present a news item in a predetermined position in front of the backing plate I2 for projection on the screen, the setting of the vanes I2 in accordance with the code combination allotted to the news displaying function will cause the operation of the function lever IIO, which when selected will rotate about the pivot 52 to raise the tail'portionupwardly to closethe contact I08 which will complete a circuit from positive battery, through contact I08, thence through relay III, and resistor II2, then over conductor II3, through the winding of the slow-to-release magnet I04, then over conductors II4 and H5 and through the resistor M6 to negative battery. The magnet I04 will become energized upon the completion of this circuit which is closed only momentarily, but which becomes locked up over a circuit traced from positive battery through the contact II'I associated with the relay III which, asis understood; has also become energizedwith the magnet-l04 causing the contact III to become closed. The locking circuit for the magnet I04 then is traced through the relay II I, resistor IIZ, conductor H3, winding of magnet I04, then over the conductors I I4 and I I5 and through the resistor I I6 to negative battery.

Under these conditions the armature I03 has been attracted so as to become disengaged from the ratchet 94, thus permitting the platen I6 to be subjected to the control of the over-running clutch to advance the paper 61 continuously until a notch 8I-N has been presented between the pair of contact rollers 'II-N and I6-N of the contactbank I9, whereupon the magnet I04 will become short-circuited over the following path: from positive battery, through the contact 1, over the conductor I I8, through the contact rollers I6'-N and 'I'I-N of the contact bank 19, thence over the conductor H9 and through the resistor II6'to negative battery. This causes the slow-to-release magnet I04 to become de-energized, as well as the locking relay III. However, due to the delayed release of the slow-to-release magnet I04, the paper 61 continues to move until it assumes theposition shown in Fig. 1 with respect to thecontacts of contact bank 19, wherein it 'is shown that the notch BI-N has passed slightly beyond the contact rollers so as to break the short circuit. Thisis to assure the operation of the paper feeding and display mechanism of the present invention in response to a succeeding news or advertisement signal combination.

When a code combination associated with the Advertisement key is received by the typing unit, the selector vanes I2 will be set characteristically to select the function lever I09 which,

through its tail portion closes the contact III! to complete a circuit from positive battery through contact Illl, thence through the relay I2I, and resistor, then over the conductor II3, through the winding of the slow-to-release magnet I04, over conductors I It and 'I I5 and through the resistance IN; to negative battery. Upon the completion of thecircuit just traced the magnet I84 and therelay' i2'i will become energized, the energization of relay IZI acting to close its contact I22 to complete a locking circuit for the magnet I04 extending from positive battery through the contact I22, then through the relay I2I, over the conductor I i3, through the winding of magnet I84, then over conductors H4 and II5 and through the resistance H6 to negative battery. This circuit will continue closed until the paper ti has been advanced, in a manner previously described, so as to bring the marginal notch 8 I-A opposite the pair of contacts I6-A and I'I-A associated with the contact bank I8. When this occurs, the previously described locking circuit will be short-circuited from positive battery, through contact I22, over conductor I23, through the contact rollers 'I6--A and 'I'IA, over conductor I24, then over conductor H5 and through the resistance I It to negative battery.

It is thus seen that upon the selective operation of the function levers I89 and I II], the paper sheet 61 containing the advertising matter and the news items is advanced under the control of the slow release magnet H14 and the pairs of contacts i6 and Ti. During normal line feed operation under the control of line feed bell crank 53, the platen i6 is rotated line-by-line or stepby-step so as to rotate the gear I02 in like manner, imparting rotation to gear 99 and pulley 98. Since counterclockwise motion is thus imparted to pulley 98 under the control of the printer line feed mechanism, and since the ratchet 94 is held against counterclockwise rotation by the armature I03, the portion 93 of the over-running clutch is free to rotate counterclockwise, thus permitting the performance of the normal line feed operation.

Should it be desired to advance the stationery 6! from one advertisement display position to another advertisement display position without pause in an intermediate news display position, operation of the invention is as follows:

By control of Advertisement key the stationery 5'! has been positioned in a first advertisement display position, not shown, in which a notch 8IA has permitted contact of rollers 'Il-A and l8--A as shown in Fig. 5 to shortcircuit magnet I04 and relay I 2I, after which the motion of the stationery 67 in direction of the arrow in Fig. 5 has drawn the notch 8I-A beyond the rollers 'I6-A and 'I'IA as illustrated at notch 8I-N in Fig. 1 and the armature of magnet I04 then has moved into retracted position to engage ratchet 94- to stop the stationery. In this condition, the Advertisement key is operated again, operating the function lover I 09 and contacts I07 momentarily, thus energizing and'operating the relay I2I and the magnet I04, starting the driving action of the stationery 6'! to be stopped when another notch 8I-A permits contact between the two rollers l6--A and 'I'IA. Obviously, the notch 8I-N Fig. 5 will permit contact between rollers 'I6N and 1'I--N before another notch 8 I-A can reach the rollers IS-A and 'I'IA but the notch 8I-N does not cause the stationery to stop. With 110 volts of electrical potential, with resistance of 2,000 ohms in resistor H6, with ohms in magnet I04 and with 100' ohms in relay I2I and resistor I25 jointly, the circuit resistance is 2,200 ohms and the current is .050 ampere. When notch 8I-N reaches rollers 16--N an'd 'I'IN and permits them to make contact, the winding of relay III'and resistor II2, having 100 ohms jointly, is connected momentarily in shunt of the winding of magnet I04, reducing the resistance of the circuit to 2,150 ohms and increasing the current to .051 ampere approximately which will divide equally between magnet I04 and marginal relay I II which by reason of its marginal nature does not operate its armature and movement of stationery B'I continues until a notch 8IA becomes efiective upon the pair of rollers l6A and 1IA to stop the stationery 61 in its next advertisement display position.
